age-tank 13 for the same puiipose.- Oftentimes, the liquid running intothe receiving tank from ythe drainage system of the building will havelarge particles which it is undesirable to have passI into thestorage-tank, and to prevent said particles from passing l into thestoragr-i-tanlr-l, a perforated screen rso or baille 24 is rigidly ,setinside the receiving-tank 3 in front of the outlet into the coupling 12, said' baffle extending from top to bottoni of the receiving-tank 3,and preferably at an inclination, so that its bottoni will be close tothe bottom of the front wall,

and its top will be substantially at the front of the inlet 7 to thetank.

Primarily, it should be understood that it often happens that gasoleneleaks from au-A tomobiles on to the iloor of the garage, and

very often. is carelessly or accidentlly spilled, and that, in eithercase, it is washed into the sewer or drainage pipes of the building inan ellort to get rid of it. ln passing into the drainage system and intothe sewer, it has been found that the oil and gas accumulate to such anextent as to produce destrhctive explosions, and. it is to prevent theseeXplosions that our apparatus is inserted either in the sewer-mainconnected with the drainage system of the building, or inthe drainagesystem itself, and the liquid, mixed of oil, gas and water, will passinto the tank '3 through the inlet 7, andwill accumulate in -the bottomofthe tank and the water only )ass into the sewer-main 1 through theoutlet and connections 4. ln the tank, the gas will naturally rise tothe to between the top of the li uid and the top oi the tank, Iwhile theoil wil naturally iioat on top ofthe water or other liquid` Since theoutlet through the main- 1 is substantially' on the level of theoverilow through the coupling 12, and since the end l of the mainextends to nearthe bottom'of the inlet-tank 3, the water will naturallypass up through or to the space the main, while the oil will overflowthrough the coupling 12 into the storage-tank 1.3., 0f course, the gaswill escafe through the vent 6, which may be erstended to the outside ofthe building by any suitable Overfiowing into the tank 13, the liquidwill. become comparatively (niet, and the water will go to the bottom, Wile the oil will iioat.

The gage will indicate the height ci the liquid in the storage-tank 13,and the oil may be drawn oil at any time through the .spigot 20, whilethe water will pass through cer/,125

2, the numeral 24indicates the oor of a garage', and 25 the sink usuallyformed therein to carry ofi' the drainage or wash fromthe vehicles instorage. Covering the sink is the usual drain or screen 26, andconnected with Athe sink is the sewer-pipe 27 which runs to the usualS-tr-ap 28, connected directly with the sewer-'main by the pipe 29.Above the bottom of the trap-portion 30, an overiiow coupling 31 isprovided, which extends to a storage-tank 32, which'is in all materialrespects substantially the same as the storagetank 13 shown in the otherforni of our invention, saidstorage-tank being provided with the s igot20, gage-tube 19 and manhole 23, allthese parts being similar to thoseillustrated in Fig. 1. The stoiage-'ta11k-is provided with the combineddrainage and ventipe 33, the lower portion, of ,which carries o i theliquid which accumulatesl in the bottom thereof, and the upper portionof which acts as a vent the same as 17, said pi e 33 being connected bythe pipe 34 to tlie coupling 35, which is connected to the sewermainconnection 29. The storage-tank 32 is also provided with a vent 36 whichmay be connected to any'ventilating pi e and conducted to the outsideofthe buil ing, and an additional vent 37 is placed in thesewerconnection at the top of the S-trap which may also be conducted tothe outside of the buildin The .mode of operation of this fori'n o, ourinvention is substantially the saine as that above described inconnection with the other forni; but, in this second form oi" ourinvention, a special form of receivingtank is unnecessary, since theS-trap takes its Cplace and` becomes the equivalent thereof an inconsequence, thel special screen or battle 24 is ehminated, since thedrain 26 performs the same function.

Having thus described our invention, what 4we claim and desire to secureby Letters Patent is:

l. The separating apparatus, having'in combination. a receiving-tank,astorage-tankcoupled thereto, a baiilawithin the receivingtant thestorage-tank, an inlet to the receivlngtank', a gas-vent in the. latter,ari outlet for the liquid'in the receiving-tank terminating' near thebottom of the latter, and yprovided with' a vent, and anoutlet for thestoragetank coupled to theA outlet for the receivingtank.

2. The separating apparatus, having in combination areceiving-tank, astorage-tank,

o prevent the passage. oi' particles to an overllow coupling between thetwo, an outlet from the receiving-tank, terminating near the bottom ofthe latter, and having the bottom of its outletassage substantially onthe level with the bottom of the overlow coupling, an outlet in thestorage-tank coupled with the outlet of the receiving-tank, and avent'in said outlet to prevent the liquid in the tank from beingsiphoned therefrom.

3. The separating ap aratus, having in combination a receptac e, meansfor connecting the same with a drainage system; a

lstorascge-tank; an overflow coupling from said receptacle to thestorage-tank; means for connecting the said receptacle and tank with asewer-system; and means for preventing particles from passinginto thestorage tank, substantially as described.

4. The separating ap aratus, having in combination a receptac e; meansfor connecting the same with a drainage system; a .storage-tank; anoverflow coupling trom said receptacle to the storage-tank; means forconnecting the said receptacle and tank with i a 4 sewer system; andmeans for ventilatin both the receptacle and thetank.

5.. In an apparatus for separating fluids of different `specificgravity7 the combination of a 1nain 'rcceptacle for all the luids; meansfor connecting said receptacle with a drainage system; an auxiliaryreceptacle; a connection between the two receptacles for passing'lluidfrom one to the other; and a normally open passage for connecting bothreceptacles with a sewer system, whereby the fluid oi greater specificgravity only is automatically passed thereby to the sewer.

`6. In an apparatus for separatingiuids of different speciic gravity,the combination. of

a main and an auxiliary receptacle; means connecting the main receptaclewith a drainage system; a connection between the two receptacles forpassing fluid from one to the other; and a normally open passage forconnecting the auxiliary receptacle with a sewer system, whereby theluid. of greater specific gravity only will automatically pass into then testimony whereof we have hereunto Asigned our names in the presenceof two subscribing witnesses. y
